I bought one ADD2 DVI card for an old HP dc7700 and found the NetBSD GENERIC kernel console fails to show a higher resolution on DVI.
- HW Selected number of Intel built-in graphic north bridge, Q965 in my case, allows ADD2 DVI card for DVI output. It's a mere Silicon Image chip to feed DVI. - Short summary i915drkms0 pauses during VGA console mode or a while and then both displays go dark. When DVI display cable is not plugged in, video mode switches to a bit higher resolution successfully, as good as so far, and everything works fine. - Details Just after power-on, dc7700 shows BIOS startup in VGA on both display, agp0 at pchb0: i965-family chipset agp0: detected 7676k stolen memory agp0: aperture at 0xe0000000, size 0x20000000 i915drmkms0 at pci0 dev 2 function 0: Intel 82965Q Integrated Graphics Device (rev. 0x02) Intel 82965Q Integrated Graphics Device (miscellaneous display, revision 0x02) at pci0 dev 2 function 1 not configured The last line might imply the cause. I can provide more diagnoses if requested. Toru Nishimura / ALKYL Technology
